Description
Technical field
The present invention relates to a kind of network digital TV field, particularly relate to a kind of by using 2 Tuner to lock frequency in advance
Point realizes the method that live television programs quickly cuts platform.
Background technology
Along with the popularization of DTV STB, Set Top Box becomes the requisite household electrical appliance of people's daily life, intelligence
Energy Set Top Box gradually replaces conventional set-top box becomes the main flow in market, has complied with television set " high Qinghua ", " networking " and " intelligence
Energyization " trend.Intelligent set top box has full open model platform, is equipped with operating system, and user is appreciating general television content
While, types of applications software can be installed and uninstalled voluntarily, it is achieved watch intelligent television program, watch that live broadcast stream media etc. is multiple
Function.
User, watching live when, can switch between each live streaming media platform, namely be commonly called as
" zapping ", switching when, player can reuse Tuner locked frequency point according to the frequency corresponding to next channel
Parsing TS data again to play out, the operation of these a series of switching channels can be interrupted current broadcasting and restart player
Often cause the phenomenons such as blank screen, time delay, card pause.
Therefore, a kind of method being highly desirable to provide fast channel to switch, reduces the shadow that Consumer's Experience is caused by zapping
Ring.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of double pre-locking methods of Tuner based on intelligent gateway, currently
When channel is play, idle Tuner is used to lock another one frequency in advance according to operating habit, can be bright when user's zapping
Aobvious shortened from frequency locking to the time play, and improved zapping speed.
In order to realize foregoing invention purpose, the present invention by the following technical solutions:
A kind of double pre-locking methods of Tuner based on intelligent gateway, comprise the following steps:
Receive the zapping instruction of channel A；
Tuner1 is used to log on to a TV channel the frequency PA of A；
After locking successfully, the code stream in this frequency is solved normal stream from Tuner1 by demodulator Demod；
Demux data stream again, uses player to commence play out video.
The method taking pre-frequency locking carries out pre-frequency locking；
Use the frequency PB of the channel B of the Tuner2 most possible zapping of locking；
Again receive zapping instruction and zapping channel is channel B；
Log on to a TV channel the most in advance the frequency PB of B due to Tuner2；
Demod can be directly begun to use to solve normal stream from Tuner2；
Demux data stream again, uses player to commence play out video；
The method the most again taking pre-frequency locking carries out pre-frequency locking；
Use the frequency PC of the channel C of the Tuner1 most possible zapping of locking；
Follow-up zapping all repeats above-mentioned identical operation.
As present invention further optimization, the selection of described channel B can be practised according to channel list order, user operation
It is used to carry out pre-judgement.
As present invention further optimization, the selection of described channel C can be practised according to channel list order, user operation
It is used to carry out pre-judgement.
Compared with prior art, the method have the advantages that
A kind of based on intelligent gateway double pre-locking methods of Tuner that the present invention provides, can be with pair pre-frequency lockings of Tuner
Save the time of locked frequency point during zapping, promote zapping speed, the blank screen of television set when reducing zapping, delay time, promote and use
Family is experienced.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of present system house dog implementation method；
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples pair
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
Fig. 1 shows a kind of double pre-locking methods of Tuner based on intelligent gateway of the present invention, comprises the following steps:
Receive the zapping instruction of channel A；
Tuner1 is used to log on to a TV channel the frequency PA of A；
After locking successfully, the code stream in this frequency is solved normal stream from Tuner1 by demodulator Demod；
Demux data stream again, uses player to commence play out video.
The method taking pre-frequency locking carries out pre-frequency locking；
Use the frequency PB of the channel B of the Tuner2 most possible zapping of locking；
Again receive zapping instruction and zapping channel is channel B；
Log on to a TV channel the most in advance the frequency PB of B due to Tuner2；
Demod can be directly begun to use to solve normal stream from Tuner2；
Demux data stream again, uses player to commence play out video；
The method the most again taking pre-frequency locking carries out pre-frequency locking；
Use the frequency PC of the channel C of the Tuner1 most possible zapping of locking；
Follow-up zapping all repeats above-mentioned identical operation.
Further preferred as embodiment, the selection of described channel B can be practised according to channel list order, user operation
It is used to carry out pre-judgement.
Further preferred as the present embodiment, the selection of described channel C can be according to channel list order, user operation
Custom carries out pre-judgement.
A kind of based on intelligent gateway double pre-locking methods of Tuner that the present embodiment provides, permissible with double pre-frequency lockings of Tuner
Save the time of locked frequency point when zapping, promote zapping speed, the blank screen of television set when reducing zapping, delay time, promote
Consumer's Experience.
Being described in detail the specific embodiment of the present invention above, but it is intended only as example, the present invention does not limit
It is formed on particular embodiments described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and
